The quality of seal structure design is related to the effect of seal and the life of seal ring. The sealing effect of the O-ring depends on the correct size of the mounting groove. The installation groove of the sealing ring is too deep, the compression of the sealing ring is not enough, so the sealing structure should be designed and processed reasonably to ensure the good sealing performance of the sealing device.

Install the sealing ring correctly to ensure the good sealing of the cement mill. Do not use tools with edges and corners to install the sealing ring, so as to avoid scratching the sealing ring and stretching it to the position of permanent deformation. The sealing ring can be properly lubricated for installation.
